Schwannome de l'oesophage cervical: Presentation d'un cas avec analyse clinique et pathologique

Neurogenic tumors for the head and neck are relatively rare and often mistaken for other disease processes. Schwannoma (neurinoma, neurilemoma, neurolemoma) is a tumour histologically characterized by the proliferation of schwann cells from the neural sheat of autonomic, cranial or peripheral nerves. We describe a case of schwannoma located in the muscular layer of the cervical esophagus. The clinical and radiological findings are highlighted allowing a retrospective preoperative presomption of schwannoma. Esophageal schwannoma is a very rare entity as only nine cases have been reported so far.
